The technical field to which the invention relates.

The present invention relates to long hollow multilateral profile. More specifically the invention relates to long hollow multilateral profile, at least one of the sides of the profile are provided bolt holes.

Below, the term "bolt hole" is used to refer to the through-hole in which the bolt is installed in a working position. Bolt hole may be, for example, round, square or rectangular cross-section. The term "mounting hole" refers to the through hole, which is used to input the bolt is in its working position.

The level of technology

During the construction of support structures, in particular for pipes and conduits often use flat profiles in the form of open angle profile or u-profile. Side profiles have bolt holes for easy connection profiles using bolts.

It is well known that public profiles, usually angular profiles, have relatively low bending stiffness, while private profiles, in particular triangular profiles, much more suitable for use as a flexible racks. Private profiles are also higher torsional stiffness.

the ri this lack of closed profiles is
the input of the bolts in the bolt holes can be complicated.

Disclosure of inventions

The present invention is to eliminate or reduce at least one of the disadvantages of the known prior art.

This problem is solved by means of the profile according to the invention, the characteristics of which are specified in the following description and in the claims.

The invention provides a lengthy hollow multilateral profile in which at least one of the parties provided bolt hole, and when the specified profile is characterized by the fact that at least one of the sides of the profile provided by the installation hole.

Thus, the bolt can be relatively easy to enter through the installation hole, and then the shank of the bolt to enter through the bolt hole and then in another component that you want to attach to the profile.

The installation hole may preferably correspond to a bolted hole, i.e. the installation hole and the bolt hole of the profile is located on close to each other.

It may be appropriate to the installation hole corresponded to the bolt holes on more than one side of the profile.

The installation hole may be oval and have the greatest length in the longitudinal direction of the profile. If this is m installation hole may correspond to a rectangular bolt holes in those cases,
when the working position of the bolt in the longitudinal direction of the profile may be different, or more bolt holes on the opposite side of the profile.

The profile can be formed in a flat profile, with the installation hole cuts through the longitudinal joint. Thus the installation hole is located on both sides of the joint planes.

The profile of this type you can get bolt and mounting holes using stamping, and then to shape the profile, for example, by way of bending or rolling.

Alternative you can use such methods of manufacture, as stamping or beading with subsequent shaping by rolling.

In the interface you can provide the connection, for example, by welding or flexible.

The profile according to the invention is suitable for profiles having a relatively high bending stiffness, and can be simply and with little complexity attached to other components. The invention provides for the use of bolts passing perpendicularly through the hollow profile and protruding from it. This saves labor and material costs.
